Here is our current test system.

Our test OS was Windows Vista Ultimate SP1 with Nvidia's 175.12 of Forceware drivers and ATI Catalyst 8.4.

We'll start things off with the idle temperatures as measured from GPUZ. Degrees are measured in Celsius.

12 degrees Celsius is quite a drop and shows great potential for the Accelero S1 Rev 2. How much will this correspond to in overclocking though? We used 3DMark 2006 to test stability and RiverTuner to push the cards clock speed.

Here we see a gain of 35MHz over the stock cooler with the GPU speed and less with the memory at 10MHz. Not bad at all though on what already was a good cooler for the GeForce 9600 GT. Here is the GPUZ screen.
